Lazer Z1 road bike helmet The Lazer Z1 road bike helmet is one of the latest additions to the High Performance Lazer helmet range. The Z1 is the lightest helmet Lazer has ever made, but is no less comfortable and safe than other helmets. The helmet is equipped with the ARS Advanced Rollsys Retention System. This allows you to adjust the fit of the helmet in an instant, ensuring that the helmet always guarantees comfort. The Adjustable Head Basket also ensures that the height is adjustable. Thanks to the In-Mold system, the helmet is extremely safe. Four different layers form one whole, resulting in optimum strength without extra, unnecessary weight. The MIPS system is an intermediate layer that is located between the EPS lining and the padding and is equipped with elastic attachments. Thanks to the MIPS system, the helmet can move relative to the head in the event of a fall, which ensures that rotational forces can be better absorbed. With a normal helmet, the impact is only absorbed by an indentation of the EPS lining. The helmet also has a notch at the forehead. Thanks to this notch, you don't look at your helmet and your field of vision is optimized. The 31 ventilation holes ensure that you don't overheat even on the hottest summer days. Cooling air flows easily penetrate the helmet while cycling. This top model was worn by professional cyclists during various UCI World Tour victories.
